Abstract

A pogo pin design that combats the short lifespan of pogo pins currently used in the final test production floor. The pogo pin is termed Spare Tip Crown Pogo Pin and is designed to mimic the standard 4 point crown pin that is widely available in today but has an additional pin tip at the middle, resulting in a 5th tip. The 5th tip is shorter than the standard operating length such that it is only triggered when the other 4 pin tips have been subjected to wear and tear, effectively acting as a spare tip to extend lifespan of the pogo pin.

The pogo pin is termed Spare Tip Crown Pogo Pin and is designed to mimic the standard 4 point crown pin that is widely available in today but has an additional pin tip at the middle, resulting in a 5th tip.  The 5th tip is shorter than the standard operating length such that it is only triggered when the other 4 pin tips have been subjected to wear and tear, effectively acting as a spare tip to extend lifespan of the pogo pin.

Body

A significant portion of cost in the test floor is used for new pogo pin purchases.  Pogo pins are constantly being used to replace worn out pogo pins to ensure excellent performance in the production floor.  A major problem is that existing pogo pins have a short lifespan due to mechanical wear and tear. In this paper we present a pogo pin design that takes this mechanical wear and tear into account and uses it to trigger a secondary contact path, prolonging total pogo pin lifespan. We call this pogo pin “Spare Tip Crown Pogo Pin”.  The pare tip crown pogo pin is exactly the same as the current 4-point crown pin used today but with an additional spare tip at the middle of the 4-point crown tip, resulting in a 5th tip. The 5th tip is shorter in length than the standard operating length so the 5th tip is not used when the pin is new. Upon repeated usage of the pogo pin, due to mechanical wear an...
